Comment 8 for bug 1882531

you can set language to german and see german context-menu on right-clicking the desktop? and your home-icon is named "Persönlicher Ordner" like in gnome-panel?

for me it looks like on desktop the language-"file" is not loaded/used.

i tried your step with Parts of the Context-Menu-Entries and most of them are not translated

frank@frank-G5-U20:~
$ echo $(gettext -d desktop-icons 'Home')
Home
frank@frank-G5-U20:~
$ echo $(gettext -d desktop-icons 'New Folder')
Neuer Ordner
frank@frank-G5-U20:~
$ echo $(gettext -d desktop-icons 'Placement')
Placement
frank@frank-G5-U20:~
$ echo $(gettext -d desktop-icons 'Sort by')
Sort by
frank@frank-G5-U20:~
$ echo $(gettext -d desktop-icons 'Open Terminal')
Open Terminal

maybe "Display Settings" is used from another application? but context-menu is also not translated...like the "New Folder" where gettext shows translation
